Re: Added a new disk, How to see it ?
1) ls -lsrt /dev/dsk
2) ls -lsrt /dev/rdsk
1) and 2) will give you the existing ones
now after adding your new disk
do
1) ioscan
2) insf -e -C disk
now do
1) ls -lsrt /dev/dsk
2) ls -ls rt /dev/rdsk
look at the date-timestamp for the last 2 entries. it should show today and current time.
do pvcreate -f on the new disk

Re: Added a new disk, How to see it ?
Thanks for all the replies, i have made progress. I have got the disk and initailised it. using
pvcreate -f /dev/rdsk/c1t2d0
Then I want to create a new volume group, so i did this
cd /dev
mkdir vgsw (vgsw being the new volume group name)
cd vgsw
mknod group c 64 0x030000
So this all worked nicely, but the next step to create the volume group is where i get this error, please help.
vgcreate /dev/vgsw /dev/dsk/c1t2d0
Increased the number of physical extents per physical volume to 35003.
vgcreate: Volume Group "/dev/vgsw" could not be created:
VGRA for the disk is too big for the specified parameters. Increase the extent size or decrase max_PVs/max_LVs andtry again.
Does anyone know how to resolve this ? Thanks

Re: Added a new disk, How to see it ?
don't try to use pvcreate -f if lun is located to somewhere else it will destroy whole data. so u should carefule to use pvcreate -f command.
if u are using pvcreate only without f it will tell u if lun is already used or not
once u got the answers u can close the thread.
thanks and regards.

Re: Added a new disk, How to see it ?
run sam --> Disks and file systems --> Disk devices --> you can see label "use underneath Unused. this can tell that the disk was not used by OS.
